METHOD OF BURNING OIL FROIVI WICKS.

Specification of Letters Patent.

Patented Oct. 1'7, 1905.

Application filed February 12, 1901. Serial No. 47,020.

' mantles and the like to incandescence without deteriorating the wickby. baking it or suffering it to receive a deposition of pyroligneousproducts; and to this and other ends hereinafter set forth the inventionstated in general terms comprises the establishment of conditionsadverse to combustion between the wick and the base of the flame; andthe invention further comprises the method of burning oil from a wickwhich consists in maintaining an interspace between the flame and thewick by feeding unbalanced supplies of finely-divided air between thewick and flame either with or without the addition of further suppliesof air between the wick and flame; and the invention further comprisesthe improvements hereinafter described and claimed.

Of course the invention can be practiced by a variety of means orinstrumentalities. However, for the sake of clearness of explanation Ihave illustrated in the accompanying drawings diagrammatic views,principally in central section, showing the invention.

In the accompanying drawingaais the wick, and the flame may be eitherunitary or subdivided, and it is designated as b b. However, in anyevent there is between the wick and the flame or the lowest portion ofit an interspace c. This interspace comprises a region of conditionsadverse to combustion. Through this interspace 0 vapors travel from thewick to the flame; but the flame may not by reason of this space bake orotherwise deleteriously affect the wick. Into this interspace 0 areintroduced unbalanced supplies of finely-divided air, and these suppliesnot only insure the existence of the interspace, but also establishconditions adverse to combustion and also prevent deposition of carbonand pyroligneous products on the wick, and since these supplies of airmay proceed from somewhat beneath the top of the wick they cause thecarbon and pyroligneous products to oxidize in the nascent state and soform gas instead of depositing.

It has been stated that the supplies of finelydivided air areunbalanced, which of course means that they are presented underdifferent conditions at the respective sides of the wick. Above theinter-space the mixture of air and vapor may be burned to produce asingle flame, or, if desired, it may be burned to produce severalflames. However, the lowest flame is in action always remote from andout of contact with the wick. The vapor in and above the "interspace maybe variously treated, as by the addition of further supplies of air tofit it for final combustion.

In the drawings, a and (0' represent wicktubes.

e and 6 represent what may be termed extensions of the wick-tubes, andthey constitute one type of means or screens for introducing unbalancedsupplies of finely-divided air into the interspace 0. To this end theymaybe made foraminous, and the openings in one of them may be differentfrom the openings in the other. As shown, the inner tube 0 is obstructedat its top and the outer tube a is proportioned to afford a spacebetween its lower portion and the wick. The introduction of air to theinterspaceor, in other words, beneath the flame-may be further modifiedby means of suitable cones or deflectors or combinations thereofas, forexample,fand air-conveyers, as f, may be used.

g indicates a chimney, and it will be understood that the wick-tube whenhollow is provided with a center draft or air-inlet and with means formoving the Wick to start and adjust the flame, and that air is admittedto the base of the chimney. It is the heat of the flame which burnsabove the interspace c that serves to vaporize oil from the wick. Theconditions which produce the introduction of unbalanced supplies offinely-divided air may be brought about by almost endless variations inthe relations of the screens a and a. For example, they may beconstructed with belts of different-sized openings or dimensions, orthey may be simply provided with belts which have no openings at all,or, again, they may simply be provided with openings of diflerentcharacters, as has been described.

It will be obvious to those skilled in the art to which the inventionrelates that modifications may be made in detail without departing fromthe spirit thereof. Hence I do not limit myself to the preciseconstruction and arrange- IIO ment of parts hereinabove set forth andillus-- trated in the accompanyingdrawings; but,

Having thus described the nature and objects of theinvention, what Iclaim as new, and desire to secure by Letters Patent, is

1. The method of burning oil from a Wick which consists in maintainingan interspace between the flame and the wick by feeding quantitativelyunbalanced supplies of finelydivided air between the wick and flame,substantially as described.

2. The method of burning oil from a Wick which consists in maintainingan interspace of vapor between the flame and the wick by feedingquantitatively unbalanced supplies of finely-divided air between theWick and flame, and feeding a supply of additional air to said vaporabove said unbalanced supplies of finelydivided air, substantially asdescribed.

3. The method of burning oil from a wick which consists in establishingat the top of the wick and between it and-flame conditions adverse tocombustion by the introduction 01' quantitatively unbalanced supplies ofair, substantially as described.

4. The method of burning oil from a Wick which consists in establishingbetween the wick and flame conditions adverse to combustion by theintroduction of quantitatively unbalanced supplies of air, andestablishing above said region adverse to combustion conditionsfavorable to combustion, substantially as described.

5. The method of burning oil from a Wick which consists in maintainingan interspace between the wick and the flame by means of quantitativelyunbalanced supplies of finelydivided air, and in subjecting both theexposed lateral surfaces of the Wick to the action of said finelydivided air thereby preventing combustion and the deposition of carbonand pyroligneous products on such surfaces, substantially as described.

In testimony whereof I have hereunto signed my name.
